Jeff,
good to see you back here, and the car back in the fold, so to speak.
I recall you were changing the rear end from a RX7 to a Celica (?). What are you running for a final ratio? And it looks that you are still on the 13" wheels. I saw you catch 2nd gear once, albeit briefly. What RPM are you using for your shift point?
I'm curious how that compares to mine. I have no plans for auto crossing, but a track day or two may be fun next year.
Thanks.
Thanks. I started with a 1st gen RX7 rear end with a 3.90 final drive. That was pretty good for autox and the size tires I typically run, but not so great for track, as it would run out of gear before getting halfway down any longish straight. I switched to a Toyota 10-bolt from an old Corolla that had a 3.31 final drive which works perfectly for the track. Naturally it isn't a great fit for autox now. The car is still on 13s, and I typically shift around 12,000rpm. I think that for autox I will need to go with some shorter tires in the rear (20") to get the gearing in a happier place. Being able to use 2nd for most of the course would make things better overall, I think.
TooBusy - Can't make it this weekend. Already have other plans, and I still need to get the fuel starving worked out.
